CLUSURE FOR SIFTER-TOP SANS.

My invention relates to closures for talcum powder cans, its main objectbeing the provision of a closure which will effectively close the sifteropenings by very simple closing operation and which is adapted to beformed economically by reason of the ease of the manufacturingoperations required.

()ther objects and advantages of the invention will be apparent as it isbetter run derstood fron the following description,

which, taken in connection with the accompanying drawings, discloses apreferred em bodiment thereof.

Referring to the drawings,

Figure l is side elevation of a container in which my invention. isembodied, the cap being shown in separated relationship;

F 2 is a top plan view thereof with the cap removed; and

Fig. 3 is an enlarged side elevation, a part thereof being broken awayand shown in section for convenience in illustration.

The container body 11 may be of any preferred form, being shown,however, as of the oblong shape now commonly in use. A top 19, isprovided with a depending flange 18 engaging over the top of the bodyand held in place by friction, or by any desired form of connection. Aneck i l is secured in a circular opening in the central part of the top153, the connection, in the present inbeing provided by means of ashoulder 15 on the exterior of said top and a flange (not shown)criinped against the in terior of the top about said opening. Sifteropenings 16 are formed in the top of said neck in any desired number orarrangement.

A removable cap 1'? is provided to close the sifter openings and asealing disk 18 of felt, or the like, is seated in the top of said cap.

As a means of tightening said cap upon the neck 14, I provideinterrupted threads 19 struck outwardly from the wall of said neck andembossed points 21 struck inwardly at intervals in the wall 22 of saidcap.

The

threads 19 are inclined from the horizontal, and upon the cap beingpositioned with the points 21 between the threads 19 and rotated. it isforced downwardly until the liner 18 is tightly held upon the top 01""the neck, thus effectively closing the sitter open- The threads 19 andembossed points 21, of course, may be easily formed by merely pressingthe metal 111 the manner indicated and the cost of production is,therefore, very small.

I claim A closure for talcum powder cans, comprising a sheet metal neckpart having a rounded top provided with sifter openings therein and withinterrputed inclined threads bent outwardly from the cylindrical wall ofsaid neck, an iinperforate cap having a rounded top conforn'iing withsaid top of the neck and rounded downward closely over the edge of theneck and thence bulged outward and thence bent inward to form a securingflange close to the neck, and inwardly ext en din GYRbOSSlHGIltS OX1flange adapted to engage under said threads of the neck, and a sealingdisk tightly and permanently confined 1n the cap under the top thereof.

JOHN M. HOTHERSALL.
